Chapter 7
Trunking System Controls
This chapter explains the trunking system control features in your radio.
7.1
Operating in Failsoft System
The failsoft system ensures continuous radio communication during a trunked system failure. If the
trunking system fails, your radio automatically switches to the failsoft channel. In a failsoft operation,
your radio transmits and receives in conventional operation on a predetermined frequency. When the
trunking system returns to normal operation, your radio automatically leaves failsoft operation and
returns to trunked operation.
Procedure:
1 To change to a different repeater frequency, rotate the Multi-Function Knob.
2 To talk, press and hold the PTT button.
3 To listen, release the PTT button.
7.2
Imbalanced Coverage
Imbalanced coverage occurs when the radio is able to receive the control channel but is unable to
transmit back to the system. The radio generates a periodic tone and displays No Comms.
7.3
Out-of-Range Radio
Your radio can no longer lock onto a control channel when out-of-range from the system.
When out-of-range, your radio shows the following indications:
• A tone sounds.
• The display shows the currently selected zone or channel combination, and out-of-range
notification.
Your radio remains in this out-of-range condition until it locks onto a control channel or failsoft channel,
or if it is turned off.
7.4
SmartZone
The SmartZone
™
feature extends communications beyond the reach of a single-trunked site (antenna
location) when operating in a SmartZone system. SmartZone units provide expanded wide-area
coverage.
SmartZone automatically switches the radio to a different site when the current site signal becomes
unacceptable. This usually happens when the vehicle in which the radio is located is driven out of the
range of one site, and into the range of another.
